FRANK B. RIVERS, OF BOYNE CITY, MICHIGAN.

AUTOMATICALLY-FEEDING OIL-CUP.

To all whom it may concern.'

Be it known that I, FRANK BYRON RIVERS, a citizen of the United States, residing at Boyne City, in the county of Charlevoix and State of Michigan, have invented certain new and useful Improvements in Automatically-Feeding Oil-Cups; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention comprehends certain new and useful improvements in oil cups and has for its primary object to provide a device o-f this character which will be of such construction and operation that the oil will be fed from the reservoir thereof to the feeding stem leading to the member or members to be oiled or lubricated by a capillary attraction.

Another objectof the invention is to provide a device of this character which will be of extremely simple and cheap construction as well as highly ellicicnt and durable in use.

The invention has for a further object to provide a device of this character which will be constructed in such manner that the amount of oil to be fed by the same to the portion of the machinery to be oiled or lubricated, may be readily regulated, as desired.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding.; of my invention reference is to be had to the following description and accompanying drawings, in which- Figure l is a longitudinal vertical section through the complete device, and Fig. Qi is a detail elevation of the feeding means and the support for the same removed.

Referring in detail to the drawings by numerals, l designates an oil cup proper or reservoir, the upper open end of which is closed by a suitable cap 2 having` its edge turned down to form the ange 3 engaged around the upper portion of said reservoir 1, when the cap 2 is in position.

Depending from the bottom of the reservoir around the outlet opening 4: thereof Specification of Letters Patent. Patr-Engg@ Aug- 232, 1916 Application filed June 2s, 1914.

is the exteriorly threaded feeding stem 5 which may be readily secured to any portion of a machine or the like to lubricate or oil parts thereof.

Projecting upwardly into the cup l is a tubular wick receiving member 6 that is of considerably less diameter than the cup l and spaced at its free end considerably from the open end of the cup l. The upper open end is preferably disposed adjacent to the center of the cup.

I have provided a wick designated 7 as an entirety that preferably consists of a number of strands of wool yarn or the like which strands are secured to one another centrally of their ends by a wick supporting member S. The lower end of the wick supporting member 8 is bent about so as to clamp the strands, as at 9. The other end of the wick supporting member is turned inwardly to form a hook l0 that is designed to engage upon the upper edge of the wick receiving member 6. The holding member S consists of a relatively spaced body portion with the hook 10 and angularly extending clamping end 9.

In operation the oil or lubricant is forced through the cup until it reaches a level below the upper working end of the tubular member 6. The wick holding member S, after the wick has been secured thereto, is inserted into the tubular member 6 and the hook end 10 thereof engaged with the upper edge of the member G so that the wick is supported. The central portion of the wick is positioned within the tubular member 6, shown in section, while the ends thereof overhang the tubular member and dispose themselves into the lubricant contained in the cup. The wick draws the lubricant upwardly and into the member 6. The lubricant drops from the lower end of the wick that is disposed within the member 6 and to the parts to' be lubricated. The stem 5 communicates with the tubular member G and both stem and tubular member are formedintegral with the cup preferably, to provide rigidity and enable cheap construction of the device as the cup and parts thereon may be cast when formed of such construction. The stem 5 is threaded and turned into the bearing or parts of the machine to be oiled.

It will be readily seen that a machine may be properly lubricated and in such manner that undue waste ,of oil is prevented. By

removing the cap 2 ready access to the wick 6 may be had, and it is only necessary to grasp the hook end 10 of the holding naember 8 to remove the wick for the purpose of clamping or renewing the same.

In practice I have found that the form of my invention, illustrated in the drawings and referred to inthe above description, as the preferred embodiment, is the most etticient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the `fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention as set forth.

IVhat is claimed is A lubricating cup comprising a cylindrical body having one end open, its opposite end being rounded and provided with a central opening, a vfeeding stem extending downwardly from said opening, its lower end being eXteriorly screw-threaded for attaching the cup in place, a wick tube extending upwardly from the opening, its upper end terminating adjacent the center of the cylindrical body, a. wick supporting member having an eye at one end and a hookY at its opposite end, said hook of the supporting member secured over the upper end of the wick tube, the eye of the same depending into said tube, a wick supported in the eye of said supporting member, the ends of said wick terminating in the bottomotl the cup, and a cover tted over the upper open end of said cylindrical body.`

In testimony whereof I atx my signature in presence of two witnesses.
